Mode-Locked Laser Made to the Size of an Optical Chip
Mode-Locked Laser Made to the Size of an Optical Chip
Researchers from the City University of New York (CUNY) Graduate Center and the California Institute of Technology (CalTech) have shrunk a mode-locked laser (MLL) to the size of an optical chip with an integrated nanophotonic platform. The results show promise for developing ultrafast nanophotonic systems for a wide range of applications.

Low-Power Optical Tweezers Shield Trapped Bioparticles from Damage
Low-Power Optical Tweezers Shield Trapped Bioparticles from Damage
Researchers at the University of Texas at Austin (UT) developed a way to overcome the intense laser heating that causes optical tweezers to scorch biological objects. The approach, called hypothermal opto-thermophoretic tweezers (HOTTs), achieves low-power — and noninvasive — trapping of diverse biological cells and colloids in their native fluids. The tweezers combine environmental cooling and localized laser heating to realize low-power, thermophoretic trapping of target objects, while simultaneously avoiding optical and thermal damage.

The Etendue Mystery Revealed The Etendue Mystery Revealed
Tue, Nov 28, 2023 10:00 AM - 11:00 AM EST
Etendue is the most important and fundamental quantity in illumination optics while simultaneously the most mysterious, misunderstood, and misused quantity. This is because, under certain conditions, etendue follows a conservation law. Similar to all conservation laws, understanding etendue provides great insight into what can be achieved with illumination optics. The confusion instead comes from understanding under what conditions etendue follows this conservation law. In this presentation, Julius Muschaweck explains what etendue is, exactly when etendue is conserved, as well as how etendue can help to assess feasibility and guide the optical designer toward finding effective optical solutions.

Design and Optimization of Optical Waveguides Design and Optimization of Optical Waveguides
Thu, Nov 30, 2023 2:00 PM - 3:00 PM EST
Optical waveguides are important building blocks for many optical devices and systems. Well-known applications range from basic optical fibers to more complex multiphysical components, such as integrated optical modulators and semiconductor optoelectronic devices for telecommunication. Moreover, waveguide devices are widely used for optical sensing and high-quality fiber laser light sources. This webinar shares about modeling optical waveguides using the Wave Optics Module, an add-on to COMSOL Multiphysics®. It covers topics such as the construction of complex waveguide structures using basic waveguide parts, the analysis of mode fields and propagation constants, and the modeling of wave propagation along optical waveguides. A representative from COMSOL introduces multiphysics couplings and shows optimization strategies while also sharing how to build and maintain custom simulation apps based on specific models, for use by colleagues or customers. Presented by COMSOL.
